In questo tutorial, ti guiderò su come configurare e installare Oracle Weblogic sul sistema operativo CentOS 7. Oracle Weblogic è uno strumento middleware ampiamente utilizzato dalle grandi aziende per servire applicazioni che utilizzano Java EE come linguaggio di programmazione. Con la sua fantastica interfaccia utente, funzionalità comprovate come il modulo di coerenza (a scopo di memorizzazione nella cache), il clustering di database (per la gestione di più connessioni di database), Oracle Weblogic mostra vantaggi piuttosto impressionanti rispetto ad altri strumenti simili come Apache Tomcat, JBoss e WebSphere. Come affermato dalla stessa Oracle, WebLogic fornisce un set completo di servizi per quei moduli e gestisce automaticamente molti dettagli del comportamento dell'applicazione, senza richiedere programmazione. Di seguito è riportato un esempio di dove si trova Oracle Weblogic in una progettazione di alto livello:
1. Nota preliminare
Per questo tutorial, utilizzerò CentOS 7.4 nella versione a 64 bit. Tieni presente che, anche se la configurazione viene eseguita in CentOS 7, i passaggi e le modifiche sono principalmente gli stessi quando si utilizza RedHat o Oracle Linux. Il motivo per cui l'ho menzionato è che la maggior parte delle installazioni di produzione per Oracle Weblogic utilizzerà Oracle Linux stesso come sistema operativo.
Alla fine di questo tutorial, saremo riusciti a visualizzare 2 nodi server che fungeranno da server gestiti Weblogic creati da un server Weblogic Admin. Oltre a ciò, utilizzeremo la dashboard di Admin Server per combinare entrambi i server gestiti in un gruppo di cluster.
2. Fase di installazione
Poiché lo scopo di Oracle Weblogic è quello di fornire codice applicativo ad alte prestazioni nel linguaggio di programmazione JAVA, è abbastanza ovvio che l'installazione per il server middleware stesso richiederebbe il runtime java per essere integrato. Pertanto, per il prerequisito di installazione, dovremo installare JAVA pacchetto nel nostro server di amministrazione e nei due nodi gestiti. I passaggi sono come di seguito:

Una volta fatto, continuiamo ad apportare modifiche al percorso dell'ambiente per creare la variabile JAVA_HOME all'interno di ogni nodo del server. Di seguito sono riportati i passaggi:
[[email protected]_mgr opt]# vi /root/.bash_profile
export JAVA_HOME=/usr/java/jdk1.8.0_131
PATH=$JAVA_HOME/bin:$PATH:$HOME/bin
export PATH

Per l'installazione del database Oracle, è requisito che l'installazione venga eseguita utilizzando un utente non root. Questo vale anche per l'installazione di Oracle Weblogic. Per quanto riguarda tale policy, per procedere creiamo un utente aggiuntivo che sarà proprietario di Oracle Weblogic. Di seguito sono riportati i passaggi:
[[email protected]_mgr opt]# useradd -s /bin/bash shahril
[[email protected]_mgr opt]# passwd shahril
Changing password for user shahril.
New password:
BAD PASSWORD: The password fails the dictionary check - it is too simplistic/systematic
Retype new password:
passwd: all authentication tokens updated successfully.
[[email protected]_mgr opt]# su - shahril
[[email protected]_mgr ~]$ pwd
/home/shahril
Prima di procedere ulteriormente, configuriamo le variabili di ambiente per l'utente proprietario di weblogic per le variabili richieste. Di seguito sono elencate le variabili di best practice da assegnare:
- ORACLE_BASE ::Posizione predefinita della directory del programma di installazione Oracle
- ORACLE_HOME ::Posizione predefinita della directory del database Oracle / facoltativa se è presente un client Oracle all'interno
- MW_HOME ::Posizione della directory di installazione del middleware predefinita
- WLS_HOME ::Posizione predefinita della directory del server gestito da Oracle Weblogic
- WL_HOME ::Posizione predefinita della directory del server di amministrazione Oracle Weblogic
- DOMAIN_BASE ::Dominio globale Oracle Weblogic predefinito
- DOMAIN_HOME ::Dominio specifico Oracle Weblogic predefinito

Una volta fatto, creiamo un file chiamato oraInst.loc e wls.rsp . Per il nome file oraInst.loc:questo file è necessario per definire un percorso di inventario durante l'installazione di Oracle Weblogic. Per il nome file wls.rsp, è facoltativo in quanto funge da file di risposta che verrà utilizzato durante l'installazione. Tuttavia, mentre procedendo faremo l'installazione dall'interfaccia della riga di comando (CLI), il wls.rsp sarebbe obbligatorio per noi avere. Ora procediamo con i passaggi come di seguito:
[[email protected]_mgr wls]$ pwd

Poiché tutto è a posto, procediamo con il download del programma di installazione di Oracle Weblogic. Puoi andare all'URL del sito web qui e scegliere la tua versione preferita di Oracle Weblogic.
Nel nostro caso, procederemo con il download di Oracle Weblogic versione 12.1.3 in quanto finora è la versione più aggiornata e stabile (basata sulla mia attuale esperienza). Di seguito sono riportati i passaggi:

Eccellente! Ora abbiamo installato con successo Oracle Weblogic sul nostro server CentOS 7. Successivamente, procederemo con la fase di configurazione.
3. Fase di configurazione
Ora siamo nella parte di configurazione, ci saranno 2 livelli di configurazione che devono essere effettuati che sono:
- Configurazione Weblogic
- Configurazione del dominio
Per un server Weblogic Administration, è necessario effettuare entrambe le configurazioni poiché il comando principale di weblogic è in configurazione weblogic. Ma per ogni server gestito da Weblogic che fungerà da nodo di istanza, è sufficiente impostare solo la configurazione Weblogic poiché durante l'inizializzazione del dominio, l'amministratore può decidere quale nodo di istanza verrà utilizzato per quale dominio di progetto. Di seguito un semplice esempio di come funziona il dominio weblogic:
Per ogni server gestito da weblogic, puoi creare tutti i nodi di istanza di cui hai bisogno, questo dipende dall'allocazione delle risorse del tuo server perché ogni nodo di istanza punterà al suo dominio di progetto dedicato. Per indicare quale dominio a quale nodo di istanza può essere facilmente eseguito dalla dashboard del server di amministrazione.
Come in breve, ora impostiamo la configurazione per weblogic e la configurazione del dominio per la parte del server di amministrazione. Giusto per semplificare il processo del tutorial, creeremo solo 1 dominio chiamato TEST. Di seguito sono riportati i passaggi:-
[[email protected]_mgr wls]$ cd $WL_HOME
[[email protected]_mgr wlserver]$ cd common/bin/
[[email protected]_mgr bin]$ ./commEnv.sh
[[email protected]_mgr bin]$ ./wlst.sh

Eccellente! Ora abbiamo effettuato la configurazione completa sulla parte del server di amministrazione. Ora, una volta terminate le parti complicate, puoi rilassarti, prendere una tazza di caffè, quindi eseguire SOLO una copia della configurazione di Weblogic e incollarla su ciascun nodo del server gestito. Di seguito sono riportati i passaggi:-

[[email protected]_mgr ~]$ scp -r /home/shahril/wls/oracle/product/fmw12/wlserver/common/templates/domains/TEST_template.jar 172.17.0.7:/home/shahril/wls/
[email protected]'s password:
TEST_template.jar 100% 50KB 58.2MB/s 00:00
Ora vai al server gestito ed estrai il file jar copiato. Non è necessaria alcuna configurazione in quanto trasferirà il dominio correlato che abbiamo creato. Di seguito sono riportati i passaggi:
[[email protected]_node1 ~]$ cd $WL_HOME
[[email protected]_node1 wlserver]$ pwd
/home/shahril/wls/oracle/product/fmw12/wlserver
[[email protected]_node1 wlserver]$ $WL_HOME/common/bin/unpack.sh -template=/home/shahril/wls/TEST_template.jar -domain=$DOMAIN_HOME

Grande! Now we have successfully configured the weblogic services on the managed servers. You can do the process to other managed server and later we will define the cluster grouping from administration server dashboard.
4. Testing Phase
To ensure that our Weblogic architecture works as expected, we'll just apply a simple test configuration on our servers. For this test, we will open the Weblogic admin server dashboard and from the dashboard console itself we will add our 2 managed servers into the environment and define them as a cluster.
Now, let's open up our admin dashboard via http://172.17.0.6:7001/console . As mentioned before, for this test, we are've just creating only 1 DOMAIN which is TEST therefore the default port 7001 are dedicated for this domain. For multiple domains, the configuration can be seperated by its own dedicated port. Once you have launched the URL in the browser, you should see the console like below, enter the username and password that we've defined during configuration above. For this test, it's weblogic/Test1234 :-
Once you have login successfully, you will see a complete dashboard like shown below:
To proceed with our test, from the dashboard click on Environment -> Servers tab . You will see the results as shown like below which automatically the Weblogic Admin server already included inside TEST domain.
Next, click on the button 
, it will forward you to page below. Fill in the Weblogic Managed Server information like it's IP addresses and the weblogic port as per shown then click next.
After that, define the new cluster name you want to the click next. Remain others as per default like example below:
Great, now you've include an instance node inside your newly created weblogic cluster. Below are the example snapshot:
Now, let's bring up the instance node. For this case, we'll go back to CLI shell and start up the weblogic managed server like command we use before like below:
[[email protected]_node1 wlserver]$ cd $DOMAIN_HOME
[[email protected]_node1 TEST]$ cd bin/
[[email protected]_node1 bin]$ ./startManagedWebLogic.sh Node_Server01 t3://172.17.0.6:7001 &
Once done, go back to admin URL and refresh the dashboard. You will see that now the instance node you've established are up and running. Below is the example screenshot:
Next, use the same process to add another Weblogic Managed Server into the defined cluster. As the final result, you will see all instance nodes you've added are up and running and in load balancing mode. Below is the example result:
Congratulazioni! Now you've successfully created a new weblogic cluster architecture.
